A hollow bow and stern, formed on the outer surface of the hull, adds to the buoyancy and aids in controlling movement of the boat.

CROSS REFERENCE TO RELATED APPLICATION The present invention is a continuation-in-part of an application filed by me in the United States Patent Ofiice on Jan. 15, 1969, under Ser. No. 791,238 for Circular Pleasure Boat.

BACKGROUND OF THE INVENTION (1) Field of the invention The present invention relates to boats and more particularly to a substantially cup-shaped boat hull having a hollow bow and stern formed on the exterior of the cup-shaped hull.

This boat is intended to enhance the pleasure of water sports and is formed in substantially circular cup-like fashion accommodating a plurality of users in a relatively safe manner.

The principal distinction of this boat over the boat disclosed in the above referred to application is the provision of the hollow bow and stem formed on the outer wall surface of the boat hull which adds to its buoyancy, enhances boat control and provides a means for mounting an outboard motor over the stern. Furthermore, the configuration of the boat hull, enhanced by sealed air compartments, results in relatively shallow draft characteristics permitting its use in relatively shallow waters.

(2) Description of the prior art Pat. No. 3,335,440 discloses a towed shallow dishshaped hull having a rotatable outer supporting platform.

SUMMARY OF THE INVENTION The boat hull is substantially cup-like in general configuration having a flat bottom integrally joined to an arcuate upwardly projecting wall. Hollow reinforcing ribs are radially formed on the inner surface of the wall and bottom of the hull. An airtight peripheral seat extends around the inner wall surface of the hull while a stabilizing air chock surrounds the outer peripheral wall. A hollow bow and stern is also formed on the outer wall surface. Central upstanding vertical walls form a well opening through the bottom of the hull which is normally closed at its upper and lower ends providing a central seat for supporting an outboard motor when the well is open. A transom, formed over the stern, supports an outboard motor.

The principal object of this invention is to provide a substantially circular boat hull having a buoyant bow and stern for controlling the boat while enjoying water sports.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the boat illustrating 3,581,327 Patented June 1, 1971 DESCRIPTION OF THE PREFERRED EMBODIMENT Like characters of reference designate like parts in those figures of the drawings in which they occur.

In the drawings:

The reference numeral 10 indicates the boat, as a whole, which is substantially cup-like in general configuration and is preferably formed by molding fiberglass material to define a substantially fiat bottom 12 integrally joined to an arcurate side wall 14. The upper edge of the side wall 14 terminates in an annular outstanding flange 16. Intermediate its height the out-er wall surface is circumferentially provided with a right angular-shaped air chock 18 having a hollow interior defined by a horizontal wall 20 and a vertical wall 22.

A bow 24 is formed on a peripheral portion of the boat including a bottom wall having a surface 26 coplanar with the boat bottom 12 and a vertical arcuate wall 28 coincident, at the forward limit of the bow, with the chock wall 22 and sealed to the arcuate outer surface of the boat. The transverse width of the bow 24 is substantially less than the diameter of the boat bottom 12.

A stern 30 is similarly formed on the boat diametrically opposite the bow comprising a bottom wall 32 coplanar with the boat bottom 12 which extends rearwardly opposite the bow and is joined to a vertical back or rear wall 34 extending vertically upward and. secured to the flange 16. The flange 16 and stern wall 34 form a transom 36 for supporting an outboard motor 38, or the like.

A keel-like ridge 40 extends diametrically across the bottom of the boat from the bow to the stern. The bottom portion 12 is provided with a central opening 42 normally closed by a plate 44. Box-like walls 46, extending upwardly within the boat, from the opening 42, form a central well 48 which is normally closed by a lid 50 to provide a seat. The well 48, in addition to forming a central seat, provides a means for mounting an outboard motor in the central portion of the boat which is accomplished by removing the lid 50 and bottom plate 44 for positioning an outboard motor therein, not shown, so that its propeller projects 'below the plane of the boat bottom 12.

The boat hull is strengthened or reinforced by a plurality of equally spaced-apart radial hollow airtight inverted V-shaped ribs 52 joinedat one end to the box wall 46 and terminating at their other end in the plane of the boat flange 16. A circular seat is formed by a substantially right angular section defining a horizontal seat 54 and a vertical seat supporting wall 56, respectively, joined to the inner surface of the hull wall 14 upwardly of its juncture of its bottom portion 12. The seat forms a hollow airtight area or chamber 58 adding to the buoyancy of the boat. The hull is further provided with a false bottom 60 overlying, in spaced relation, the bottom portion 12 and overlying that portion of the ribs 52 extending radially across the bottom 12. The false bottom 60 thus forms additional air pockets between the respective ribs 52 which further adds to the buoyancy of the boat.

Obviously the invention is susceptible to changes or alterations without defeating its practicability, therefore, I do not wish to be confined to the preferred embodiment shown in the drawings and described herein.
